NOTICE

Cooling SystemThis Bard cooling system is composed of MULTI-TEC, FUSION-TEC WR Series and/or MEGA-TEC wall-mounted air conditioners matched with an LC6000 controller or Bard th-Tune stand-alone controller (th-Tune can only be used with MULTI-TEC units). If only one wall-mounted air conditioner is being used, it can be matched with either the LC6000 or a th-Tune stand-alone controller (if applicable). If more than one wall-mount unit is installed, the LC6000 controller must be matched with the air conditioning units. The wall-mount units are specifically engineered for equipment cooling applications.

NOTE: The LC6000 controller and MULTI-TEC, FUSION-TEC WR Series and MEGA-TEC wall-mount units are designed specifically to work together. The controller cannot run other brands of systems, nor can other controllers run the MULTI-TEC, FUSION-TEC WR Series or MEGA-TEC wall-mount units. They are a complete system, and must be used together.

1 One remote temperature/humidity sensor is included with the LC6000 controller. If the site in which the LC6000 controller will be used has more than one zone (maximum three zones per LC6000), additional remote temperature/humidity sensors (one sensor per zone) will need to be purchased and installed in the additional zones. One additional temperature-only sensor (Bard P/N 8301-058) may also be used in Zone 1 but will also need to be purchased separately. Additional temperature/humidity sensors require field-supplied 5-wire 18 gauge shielded cable. Temperature-only sensors require field-supplied 2-wire 18 gauge shielded cable.

Emergency Off Alarm

If the LC gets an input from a smoke detector or similar device, an alarm will be generated and all units will be shut down. Additionally, a relay output will be actuated from the LC to provide remote notification of the event.

The emergency off input can be configured to accept either normally open or normally closed inputs. The controller is defaulted to normally open and a jumper is placed across the terminals of the input (#6 and #7). When this jumper is removed, the alarm will become active.

To change the direction of the emergency off input:




4. Press UP or DOWN keys to scroll to Digital In Config C1.

5. Press ENTER key to scroll to the variable in the table that intersects EM Off and Dir (see Figure 3).


Emergency Off (EM Off) Dir (direction) is the position of the smoke detector contacts in the event of smoke. NO is normally open; NC is normally closed.

EM Off En (enable) allows the LC control to monitor the smoke detector when set to ON. When set to OFF, the LC controller ignores the smoke detector.

EM Off Val (value) of ON indicates a smoke event. A Val (value) of OFF indicates no smoke event.

Smoke detector connections (emergency off input) are on the LC6000 terminal block; see Table 6 on page 24 for terminal block index.

FIGURE 3Adjust Emergency Off, Emergency Vent or

Generator Alarm Input Direction


Generator Alarm

If the LC detects a generator running event (through a digital input), an alarm will be generated. Additionally, a relay output will be actuated from the LC to provide remote notification of the event. The end user will be able to configure which units are permitted to run during this event. Default will be to not allow any units to run.

The generator alarm input can be configured to accept either normally open or normally closed inputs. The controller is defaulted to normally open and a jumper is placed across the terminals of the input (#10 and #11). When this jumper is removed, the alarm will become active.

To change the direction of the generator input:





5. Press ENTER key to scroll to the variable in the table that intersects Gen and Dir (see Figure 3).


Gen Dir (direction) is the position of the generator input contacts in the event of a need for generator operation. NO is normally open; NC is normally closed.

Gen En (enable) allows the LC control to monitor the generator input contacts when set to ON. When set to OFF, the LC controller ignores the generator input contacts.

Gen Val (value) of ON indicates the generator is in operation. A Val (value) of OFF indicates the generator is not operating.

Generator connections (generator run input) are on the LC6000 terminal block; see Table 5 on page 22 for terminal block index.

While the generator is running, the system will only allow selected units to run. This selection is customizable by the end user. This limitation is in place to match the unit power requirements to the shelter generator capacity.

The default is to not allow any units to run during a generator event. This can be adjusted to allow specific units to run during a generator event.

The generator alarm notification relay has dry contacts. The Dir (direction) is the position of the relay without generator operation. NO is normally open; NC is normally closed.

When the Val (value) is ON, the relay is in an alarm condition. The relay connections (generator alarm) are on the LC6000 terminal block; see Table 6 on page 24 for terminal block index.

Emergency Vent Alarm

If the emergency vent terminals are activated by a hydrogen detector or similar device, an alarm will be generated and the wall units will all be put into emergency ventilation by the LC. Additionally, a relay output will be actuated from the LC to provide remote notification of the event. The end user will be able to configure which zones ventilate during this event.

Units with economizers will operate in emergency vent mode. The dampers will open at 100% and the blower will come on at full speed until the alarm is reset. Units without economizers located in the same zone will only bring on the blower at full speed.

The emergency vent alarm input can be configured to accept either normally open or normally closed inputs. The controller is defaulted to normally open and a jumper is placed across the terminals of the input (#8 and #9). When this jumper is removed, the alarm will become active.

To change the direction of the emergency vent input:





5. Press ENTER key to scroll to the variable in the table that intersects EM Vent and Dir (see Figure 3 on page 6).


Emergency Vent (EM Vent) Dir (direction) is the position of the emergency vent contacts in the event of hydrogen being sensed. NO is normally open; NC is normally closed.

EM Vent En (enable) allows the LC control to monitor the hydrogen detector when set to ON. When set to OFF, the LC controller ignores the hydrogen detector.

EM Vent Val (value) of ON indicates a hydrogen event. A Val (value) of OFF indicates no hydrogen event.

Emergency vent connections (hydrogen detector input) are on the LC6000 terminal block; see Table 6 on page 24 for terminal block index.






5. Press ENTER key to scroll to the variable in the table that intersects EMG Vent and Dir (see Figure 4 on page 7).


The emergency vent alarm notification relay has dry contacts. The Dir (direction) is the position of the relay without a hydrogen event. NO is normally open; NC is normally closed.

When the Val (value) is ON, the relay is in an alarm condition. The relay connections (emergency vent alarm) are on the LC6000 terminal block; see Table 6 on page 24 for terminal block index.

Zone Unit Alarm

By default, if any of the units communicate a high pressure or low pressure alarm to the LC, the LC will actuate a relay output to provide remote notification of the event. A relay output will be actuated from the


FIGURE 6Adjust Zone Alarm Configuration

LC to provide remote notification of the event for each zone.






5. Press ENTER key to scroll to the variable in the table that intersects Z1Alm and Dir, Z2Alm and Dir, or Z3Alm and Dir (see Figure 2 on page 5).


When the direction is set to NO, the relay output will be closed when the alarm is active and open when not active. When the direction is set to NC, the relay output will be open when alarm is active and closed when not active.

The zone alarms can be configured to actuate based on 15 alarms communicated from each wall unit. These items can be selected for each zone.

To select which wall unit alarms actuate zone alarms:



3. Press UP or DOWN keys to scroll to Adv Sys Config; press ENTER key.

4. Press UP or DOWN keys to scroll to Zone Alarm Config B4, Zone Alarm Config B5 and Zone Alarm Config B6. The 15 alarms are divided between these three screens.

6. Press UP or DOWN key to change value (N or Y). If a value of Y is entered, the wall unit alarm will trigger the zone alarm relay output. If a value of N is entered, the wall unit alarm will not trigger the zone alarm relay output.

NOTE: By default, only 'no temperature sensors' and high and low pressure actuate the alarms.

NOTE: Power Loss group is also affected by communication loss.

NOTE: If no temperature sensors are detected by the controller for a given zone, that zone alarm output will be actuated. This is nonconfigurable.

Humidity Alarm

When the LC detects a high indoor humidity or low indoor humidity event in a selected zone (through an analog input from a remote sensor), an alarm will be generated. Additionally, a relay output will be actuated from the LC to provide remote notification of the event. The end user can configure the alarm to be actuated when the measurement is high, low or both high and low.

FIGURE 8Change Indoor Temperature Averaging Type

CONTROL OPERATION

NOTE: Screenshots shown in this manual reflect default settings (when applicable).

Temperature ControlIndoor Temperature Averaging

The LC has the ability to average all of the zone temperature sensors connected to the LC and the return air temperature sensors connected to the wall-mount unit, use only the zone temperature sensors, or use the LC sensors and any unit which has its blower run continuously. This can be set differently for each zone. This value will then be used as a zone indoor temperature for the LC and wall-mount unit control functions.

There are three possible sensor averaging selections:

• LC Only

This configuration only averages the zone temperature sensors connected to the LC and enabled within the specific zone.

• Blower On

This configuration averages any temperature sensors connected to the LC that are enabled and the return air temperature sensor of any wall-mount unit set to run in continuous blower within the specific zone.

• All Sensors

This configuration averages the zone temperature sensors connected to the LC that are enabled and all the return air temperature sensors of all wall-mount units within the specific zone, regardless of blower operation.

To change the indoor temperature averaging type:





5. Press UP or DOWN keys to scroll to Zone Temp A2-11 (Zone 1), Zone Temp A3-11 (Zone 2) or Zone Temp A4-11 (Zone 3).

6. Press ENTER key to scroll to Selection (see Figure 8).

7. Press UP and DOWN keys to adjust.

Comfort Mode

If comfort mode is activated, all of the zone setpoints will be set to 72°F for cooling and 70°F (Comfort Setoint -2) for heating. This setpoint will be active for 60 minutes.

To enable comfort mode:

1. Press UP or DOWN key while on the Status screen to select Setpoints ( ) from the Quick Menu options; press ENTER key.

2. Press ENTER key to scroll to Comfort Mode.

6. Press ENTER key to scroll to Comfort Enable.

7. Press UP or DOWN key to change value from OFF to ON; press ENTER key.

The system is now in comfort mode and will cool or heat to the comfort setpoint for the 60-minute duration.

StagingEach zone is capable of three different staging methods.

FIFO (First in First Out)

The unit that is first in rotation will be the first one turned off.

LIFO (Last in First Out)

The unit that is last in rotation will be the first one turned off.

Demand Staging

While in cooling operation, the unit with the highest return temperature will be brought on first. The unit with the lowest return temperature will be turned off first. While in heating mode, the unit with the lowest


return air temperature will be brought on first and the unit with the highest return temperature will be turned off first.

To change the staging method type:





5. Press UP or DOWN keys to scroll to Staging A2-5 (Zone 1), A3-5 (Zone 2) or A4-5 (Zone 3).

6. Press ENTER key to scroll to the variable labeled Type (see Figure 9).

FIGURE 11Rotation

Demand

The system will compare the zone temperature (determined by zone averaging selection) to the zone cooling and heating setpoint. A demand will be calculated to determine how many units are required.

For cooling, the zone temperature will be compared to the cooling setpoint. The controller will calculate a demand based on how far above the setpoint and how long it has been above the setpoint. The demand value (0-100%) will then be split and applied to free cooling and cooling separately shown as two demands both ranged 0-100% applied to all of the available cooling methods for that zone. For example, if the demand is at 50% and there are 10 available stages of cooling in that zone, there would be 5 stages active (50% x 10 = 5). The system will prioritize free cooling stages over compressor stages. Adding to the example, if 5 of the 10 stages for cooling are economizer, 5 units would be running economizer and no compressors running. The demand is calculated for the cooling application. However, for display purposes, the demand is split so that the user can see demand separately for free cooling and compressor.

For heating, the zone temperature will be compared to the heating setpoint. The controller will calculate a demand based on how far below the setpoint and how long it has been below the setpoint. The demand value 0-100% will the be applied to all of the available stages of heating in that zone. For example, if the demand is at 50% and there are 5 available stages of heating in that zone, there would be 2 stages active (50% x 5 = 2.5 and a half of a stage cannot be turned on).

Humidity ControlThe LC can be configured to control up to three humidifiers (field supplied) with relay outputs and up to 14 units equipped with dehumidification. The indoor humidity level for each zone is compared to the dehumidification setpoint and humidification setpoint for each zone.

Dehumidification

The LC6000 controller will monitor the indoor relative humidity of each zone and compare the value to three setpoints for each zone. The three setpoints will be described as dehumidification off, passive dehumidification and active dehumidification. The default value for these setpoints will be 60%RH, 70%RH and 80%RH, respectively.

When the humidity level inside the shelter falls to the dehumidification off setpoint, the system will stop attempting to dehumidify the space.

When the humidity level rises to the passive dehumidification setpoint, all units with economizers will disable the use of economizers for cooling calls. This will act as passive dehumidification by forcing the use of compressor for space cooling. Availability for passive dehumidification will be determined by model number. All units with economizers will be considered.

When the humidity level rises to the active dehumidification setpoint, the controller will activate staged dehumidification. The controller will then calculate a dehumidification demand based on how far above the setpoint and how long the RH level has been above the setpoint. The demand will then utilize all of the units with active dehumidification capabilities to reduce the indoor humidity level. The units will be staged on based on the existing cooling rotation for the units in the zone up to an optional maximum number of units running value. Availability for active dehumidification will be determined by model number. Units with concurrent electric reheat or mechanical dehumidification will be considered. NOTE: Only one type of dehumidification unit will be considered depending upon configuration of the LC6000 controller. Unit capability is determined by the model number.

To change the dehumidification setpoints:

NOTE:

Wire indexes are identified such that even numbered index numbers are on the lower wire entries of the terminal block and odd numbered index numbers are on the top wire entries. Since terminal block 60 is a ground block, terminal blocks 61 thru 72 shift while still maintaining the same top and bottom configuration.
